Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00932 | $0.00932 |
| Opus 5.5 | $0.00373 | $0.00373 |
| Sonnet 5.5 | $0.00186 | $0.00186 |
| Haiku 4.5 | $0.00093 | $0.00093 |
Grade A, and why
init-claude-md CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
91% identical to init-claude-md AGENTS.md — 3 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Session Maintenance Protocol
开始时：读 TODO.md，复述当前 🔴 和 🟡 段；扫 references/ 是否与 SKILL.md 描述一致。
结束前（最后一条用户消息之后、停止前必做）：
- 回看本次会话实际做了什么 —— 改动的文件、发现的问题、用户新增的约束
- 更新
TODO.md（决策表见references/session-maintenance-protocol.md） - 更新本文件的规则 —— 本次会话暴露的新约定加到对应段
- 刷新日期戳
> 最后更新：YYYY-MM-DD
触发条件：≥1 个仓库文件被改 · 用户新增约束 · 会话 > 10 分钟
Core rules (from Karpathy)
- Think Before Coding — surface assumptions, push back when warranted
- Simplicity First — minimum code that solves the problem
- Surgical Changes — touch only what you must
- Goal-Driven Execution — define success criteria, loop until verified
Language
- Communication:
zh（用户偏好） - Code comments:
zh - Commit messages:
en（Conventional Commits 必须英文） - Rule files:
zh
Project conventions
- 纯 Markdown skill：没有代码 / 包管理器 / 测试运行器
- 编辑
SKILL.md时必须同步更新references/和examples/（决策表、模板、检测矩阵三者锁步） - 所有文件统一用 UTF-8 no BOM（PowerShell
Set-Content -Encoding UTF8默认带 BOM，禁止用） references/session-maintenance-protocol.md是 single source of truth，根文件里的短版必须与之保持一致
Workflow
- Branch:
codex/<scope>-<slug>（solo 维护时直接用 main，feature branch 可选） - Commit: Conventional Commits（
feat:,fix:,chore:,docs:,refactor:） - Solo 维护者：直接
git push origin main，commit log 即 audit trail - TODO.md：每次会话结束时按决策表更新
Verification
git diff --stat HEAD 确认改动符合预期；改 SKILL.md 后用 Get-Content -Encoding UTF8 检查没有 BOM。
Things to avoid
- 不要在 skill 主体加 TypeScript / 任何编译型语言
- 不要加 CI 依赖（这个 skill 没必要要求 Node 18+ 才能用）
- 不要改
SKILL.md时漏改references/（决策表 / 模板 / 检测矩阵三者必须锁步） - 不要写带 BOM 的 UTF-8 文件（PowerShell 默认行为）
- 不要从
examples/删文件而不补 README 的目录树 - 不要在 README 里用单反引号包裹多行内容（GitHub 会渲染成一行）。多行示例一律用 fenced code block (
```text或```markdown)；嵌套示例用 4 个反引号 - 不要把
description字段里的中文触发词写错（之前是涓?乱码，每个 agent 看到的触发词是错的） - 不要用 PowerShell Get-Content | Set-Content 改 Markdown（CRLF 会丢成 LF-only、\a \b \v 会被 PS 解释成控制字符）。用 [System.IO.File]::ReadAllBytes/WriteAllBytes 字节级操作
- 不要在 skill 里加 hook / cron / 外部触发器（软自动才是设计核心；外部触发器破坏跨 agent 兼容）
- 不要去掉根文件顶部的

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

init-claude-md CLAUDE.md is an instructions file published in the GitHub repository LetheChen/init-claude-md (1 stars, last pushed 3mo ago), licensed MIT. It adds 932 tokens to every session, about $0.0037 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 91% identical to init-claude-md AGENTS.md, differing in 3 lines, and is treated as a copy.
